The Advanced eXtensible Interface(AXI) bus is a high-performance parallel bus that connects on-chip peripheral circuits (or IP blocks) to processor cores. The AXI bus employs "channels" to divide read and write transactions into semi-independent activities that can run at their own pace. The Read Address and Read Data channels send data from the target to the initiator, whereas the Write Address, Write Data, and Write Response channels transfer data from the initiator to the target.
